+// This test case is a reduced case of a caching bug discovered by an
+// assertion failure in RegionStoreManager::BindArray.  Essentially the
+// DeclStmt is evaluated twice, but on the second loop iteration the
+// engine caches out.  Previously a false transition would cause UnknownVal
+// to bind to the variable, firing an assertion failure.  This bug was fixed
+// in r76262.
